Dara Ó Briain competed on series 14 of the British comedy show Taskmaster in 2022, where comedians tackle absurd tasks for Greg Davies and Alex Horne. His quick, deadpan confusion became a fan favourite, and short reaction lines like this wait, what were clipped for soundboards and social edits. Creators now use it as a universal shorthand for disbelief, in the same family as other British panel-show reactions. It endures because the delivery is instantly readable even without context, fitting any moment that needs a fast, funny double-take.
